Greg, I had an idea about device drivers and self-tests. Create a compiler tag called __selftest which would function similar to __init. A device driver author could write directly into their kernel module self-test functions identified with this tag. Using the tag, the person compiling the kernel could: 1) Completely remove the code/data at compile-time. 2) Have the code run once at boot and then free the memory after a single use. 3) Leave the code in place and expose it to userland via the debugfs filesystem. Users could run the tests at their pleasure. It would be an opt-in system, so existing drivers could have the code added at your leisure. What are your thoughts on this idea? - Matthew Whitehead _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
